NAP-RAISING- MACHINE FOR FELT HATS.

To all whom it may concern.

Be it known that 1, JOHN H. STARR, a citizen of the United States,residing at Danbury, county of F airfield, State of Connecticut, haveinvented an Improvement in Nap- Raising Machines for Felt Hats, of whichthe following is a specification.

This invention relates to the manufacture of nap felt hats and has forits object to provide a simple, inexpensive and thoroughly effectivemachine for raising the nap upon the bodies, the operation being knownin the art as jacking.

With this end in view I have devised the novel machine, of which thefollowing description in connection with the accompanying drawings is aspecification, reference characters being used to indicate the severalparts:

Figure 1 is a view of my novel machine, partly in elevation and partlyin vertical section, showing a hat body in position on the cone; Fig. 2a side elevation corresponding with Fig. 1; Fig. 3 a front elevation ofthe machine, the view being from the right in Fig. 2 but showing adifferent style of cone; and Fig. 3 is a View showing the use of atapering secondary nap raising roller.

An import-ant feature of the present machine is that it performs twoindependent jacking operations, the secondary operation being performedby a retarded roller which is rotated by the hat body on the cone.

denotes the framework, 11 the body carrying cone, 12 the primary napraising roller, 13 the cleaning roller, 14 the secondary nap raisingroller and 15 a hat body on the cone. The cone is provided in its underside with a socket having a metal bushing 16. This bushing is shown astapering inward and receives closely the correspondingly tapered end ofa shaft 17 which is stepped in a bear- The end of the shaft bears upon ablock 19 which rests upon a set screw 20 by which the shaft may beraised or lowered to adjust the height of the cone and locked at thedesired adjustment by a set nut 25. The primary nap raising rollerand'the cleaning roller are journaled on a bracket 21, which is pivotedon a cross rod 22 forming "part of a yoke 23 itself pivoted as at 55 toarms 24 rigidly secured to and extending from the framework.

The yoke is locked at any required adjust- Specification of LettersPatent.

ment, depending upon the shape of the cone, by means of nuts 26 on athreaded rod 28, forming part of the frame, which passes through an arcslot in an arm 29 which is rigidly secured as by set screws to cross rod22. The pressure of the primary nap raising roller upon a hat body onthe cone is determined by means of a spring 30 and chain or rodconnections intermediate bracket 21 and an operating lever 31. Thetension of the spring is adjusted by means of a turn buckle 32. Theoperating lever is shown as pivoted to an arm 33 extending from theframework and is itself provided with an angle arm 34' to which the turnbuckle is connected. A cross bar 35 on the framework or any suitablestop is provided to limit the movement of the operating lever inswinging to the operative position. When this lever is swung downagainst the stop, as in Fig. 1, the nap raising roller will be drawn bythe spring into close engagement with the hat body on the cone, and whenthe lever is swung into' the position indicated by dotted lines, thepull of the spring upon the bracket and roller will be relieved and theweight of the bracket will swing the roller out of engagement with thehat body, the outward movement of the roller being limited by theengagement of angle arm 34 on the lever with the framework.

The primary nap raising roller is driven by means of a belt (not shown)passing over a pulley 36 on the shaft of the roller. At the ends of theshafts of the primary nap raising and the cleaning rollers arerelatively large and small belt pulleys 37 over which a crossed belt 38passes which drives the cleaning roller. As the pulley on' the cleaningroller shaft is smaller than the other pulley, the cleaning roller isdriven faster than the nap raising roller and acts to clean it andprevent clogging. The secondary nap raising roller is journaled in abracket 39 which is pivoted on a cross rod 40 forming part of a yoke 41itself pivoted, as at 57, to arms 42 rigidly secured to and extendingfrom the framework. The yoke is locked at any required adjustmentdepending upon the shape of the cone by means of nuts 43 on a threadedrod 44, forming part of the frame, which passes through an arc slot inan arm 45 which is rigidly secured as by set screws 56'- to cross rod40.

The pressure of the secondary nap raising roller upon a hat body on thecone is determined by means of a spring 46 and flexible connectionsshown as passing over a pulley on the bracket and including a strap 47which passes over a pulley 58 on the roller shaft and the other end ofwhich (not shown) is connected to any suitable fixed portion of themachine. The tension of the spring, which also determines the drag uponor retardation of the roller, making ita nap raising roller, is adjustedby'means of a turn buckle 48. The other end of the flexible connectionpasses over a pulley 4:9 and is connected to an angle arm on anoperating lever 50 which is identical in construction and operation withlever 81 and is similarly pivoted to an arm 83. When this operatinglever is swung downward, as in Fig. 3, the roller will be drawn by thespring into close engagement with the hat body on the cone, and when thelever is swung upward the pull upon the bracket and roller will berelieved and the weight of the bracket will swing the roller out ofengagement with the hat body. In practice, suflicient tension is givento spring 16 to cause it to appreciably retard roller 14 and thus makeit effective as a nap raising roller.

While the invention is not limited to any special construction ofprimary and second ary nap raising rollers, I preferably make saidrollers of uniform diameter from end to end and cover them with stripsof card cloth, indicated by 51, wound spirally from end to end of therollers. The cleaning roller is provided on its periphery with twolongitudinal strips of card cloth, indicated by 52, with spaces 53between them.

In Fig. 3", I have shown the use of a tapering secondary nap raisingroller which is indicated by 5 1.

The operation of the machine is as fol-' lows: The primary nap raisingroller which is driven performs the first nap raising or jackingoperation and also causes rotation of the hat body and cone. Thesecondary nap raising roller performs a second nap raising or jackingoperation. This roller, which is non driven, is rotated through itsengagement with the hat body but as its rotation is retarded by strap 47and the spring it jacks the body, that is picks up the nap the same asthe other roller, the primary or driven nap raising roller acting topull the nap forward and the secondary or retarded nap raising rollerpulling the nap backward as the body is drawn under it by the drivenroller. The amount of drag or retardation of the secondary nap raisingroller is determined by the tension of spring 16 which is regulated byturn buckle 4:8. The pressure of the primary nap raising roller upon thehat body is determined by spring 30 which is adjusted by turn buckle 32.As

cleaning roller 13 is caused to rotate faster than the primary napraising roller it acts to clean said roller and prevent it fromclogging. In order that the operator may have independent control of thenap raising rollers, each is connected to a separate operating lever. Instarting, the operator throws both of the operating levers to theinoperative position, as indicated by dotted lines in Fig. 1. Thisrelieves the tension of springs 80 and 4:6 and the weight of thebrackets by which the rollers are carried will cause them to swingdownward on their pivots and raise the rollers away from the cone. Thisis done without stopping the rotation of the primary nap raising roller,which is the only element of the machine to which power is directlyapplied. Having placed a body in position on the cone, the operatorswings both operating levers to the operative position as shown in fulllines in the drawings. When the jacking operation is completed theoperator swings the levers to the inoperative position, which causes thenap raising rollers to swing away from the cone and enables the operatorto remove the jacked body and place another body on the cone in positionto be operated upon.
